我在执行命令时收到以下错误：npm start

[nodemon] app crashed - waiting for file changes before starting...

package.json 文件：

  "name": "essentials",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "start": "nodemon ./index.js --exec babel-node -e js"
  },

    "babel-preset-env": "^1.6.1",

  }
}

我按照以下链接进行操作，但仍然没有一个对我有用。

我还看到以下警告消息：

加载参考“ https://schemastore.azurewebsites.net/schemas/json/package.json ”时出现问题：无法从“ https://schemastore.azurewebsites.net/schemas/json/package.json ”加载架构：无法连接到https://schemastore.azurewebsites.net/schemas/json/package.json。错误：证书链中的自签名证书

谁能帮我解决这个问题？

包名应该是lodash，不是loadash。

在您更正之后，packages.json 您需要执行npm install.
